# Presto

Presto is a distributed query engine for analyzing big data using SQL queries. With UI Bakery, you can build applications on top of your Presto API in just a couple of minutes.

## Configuration

### Connecting the data source

1. On the **Data sources** page, click **Connect**, and select *Presto* in the Data sources list.
2. Specify the **JDBC connection string**, for example:

```
jdbc:presto://presto-host.com:8080
```

{% hint style="info" %}
UI Bakery connects to Presto using JDBC - you will need to create a JDBC string to connect your data source.
{% endhint %}

3. Next, fill in all other required credentials and click **Test connection** to check whether the data source can be connected.
4. Click **Connect Datasource** to complete the setup.

## Usage

Currently, UI Bakery only supports the [SQL Query](https://docs.uibakery.io/reference/working-with-actions/sql-query) action step when working with Presto data sources.
